Grinding is used in many applications during final finishing of heat-treated parts. It is a high-energy process with much of the energy converted to heat. This heat can cause detrimental residual stress and microstructural changes that can reduce product life. Proper control of the grinding operation is critical to reduce grinding burn. References
Aug 11, 2020· You can also try to stop grinding your teeth by managing stress and practicing jaw exercises. If left untreated, teeth grinding can cause enamel loss, receding gums, and chipped teeth.
It is also a low stress machining operation that avoids potential metallurgical damage associated with conventional grinding machines, including cracking and heat distortion. This makes ECG ideal for machining of delicate and thin walled parts. In addition, the electrolytic process can break sharp edges leaving a radius of .001 to .005 ...
